Hello,

I have configured the xorg to allow multiplies users in one linux
machine (like Userful application).

But i have one problem that a user can shutdown the machine. I only
allow the users to close the session.

Who i make to disable the shutdown and reboot options from gnome menu
to all users.

Tanks
